Master Kubernetes with this a 4-day Advanced Kubernetes workshop on the 22nd of September (in 2 weeks)!

_What should you expect?_

- Learn how to architect and design clusters from the ground up (in the cloud or on-prem).
- Explore the Kubernetes internal component and how the system is designed with resiliency in mind.
- **Deep-dive into the networking components and observe the packets flowing into the cluster.
- Hands-on labs to test the theory with real-world scenarios!

k8shorizmetrics is a library that provides the internal workings of the Kubernetes Horizontal Pod Autoscaler (HPA) wrapped up in a simple API.

The project allows querying metrics just as the HPA does, and also running the calculations.

This article will look into how you can secure Ingress resources via adding TLS to Ingress and then procuring TLS/SSL certificates.

In this repository, you will find a collection of mini-programs covering various client-go use cases inspired by client-go/examples. The intention is to test (more or less) a fresh version of Go and packages against a few latest Kubernetes versions.

The article starts with a recap of Kubernetes resource management and its core concepts of requests and limits.

Then it discusses those static limits in the realm of pod autoscalers, such as HPA, VPA, and KPA.

In this article, you'll learn how to build a distributed Jenkins cluster on GKE and autoscale the Jenkins agents to process more jobs.

Reducing infrastructure costs boils down to turning apps off when you don't use them.

However, the challenge is figuring out how to turn them on automatically when needed.

Take the example of a Kubernetes dev cluster: you might want not to run any service during the weekend.

In this webinar, Salman will demo live how you can use KEDA and the HTTP scaler to intercept and monitor the requests to your services and scale your pods accordingly.

In the process, you will discover how you can scale to zero and create pods only when you need them.

Over 900k Kubernetes exposures were observed across the internet during a routine threat-hunting exercise.

While this does not imply that all exposed instances are vulnerable to attacks, it still makes them a target.

You can learn more in this report.

All unpatched versions of Argo CD starting with v1.3.0 are vulnerable to a symlink following bug allowing a malicious user with repository write access to leak sensitive YAML files from Argo CD's repo-server.

operator-lifecycle-manager is a management framework for extending Kubernetes with Operators.

OLM extends Kubernetes to provide a declarative way to install, manage, and upgrade Operators and their dependencies in a cluster.

Octopilot is a CLI tool designed to help you automate your Gitops workflow, by automatically creating and merging GitHub Pull Requests to update specific content in Git repositories.

When your Kubernetes cluster runs low on resources, the Cluster Autoscaler provision a new node and adds it to the cluster.

The cloud provider has to create a virtual machine from scratch, provision it and connect it to the cluster.

The process could take more than a few minutes from start to end.

But there's an alternative: you can proactively create nodes that are already provisioned when you need them.

In this webinar, Chris will demo live how you can configure Pod Priorities and a placeholder pod to pre-warm node instances for quicker scaling.
